Now, officials are trying to figure out if it's connected to a bank robbery. FBI investigators are in Danbury to help police with their investigation.
It was a chaotic day for students, parents and police. At a firehouse, frantic parents came to pick up their kids after their school was evacuated. Around 9:30 a.m., a bomb threat was called in to the King Street Primary School.
"Having lived in Danbury for 20 years, this is the worst I've seen of someone pulling a stunt like this," parent Joe Cocco said.
A short time later, another threat, this one claiming a toxic gas would be released, was called in to Danbury High School, which was also evacuated.
At that point, the decision was made to dismiss all public, private and parochial schools in Danbury. Meantime, back at the elementary school, investigators found a suspicious device exactly where the caller said it would be.
"The nature of that device is being investigated, but it's not believed to be explosive," Danbury Mayor Mark Boughton said.
Police are not sure if the threats were called in as a diversion because just after 10 a.m., a Bank of America branch on the other side of town was robbed.
The suspect in the robbery managed to escape on a bicycle, wearing a straw hat.
